North Korea has not been answering routine phone calls from South Korea through an inter-Korean communication channel for six days, APA reports citing Yonhap News Agency.
The calls are made twice daily, and the North has not responded to the opening calls.
The two Koreas decided to reestablish the hotline last year after it was cut off by Pyongyang in June of 2021 over Seoul's alleged attempts to spread anti-government information across the border, after which the North entered several areas disarmed under inter-Korean agreements.
